The Asian Development Outlook (ADO) breaks down the role of Asia and the Pacific region in what could be the greatest challenge faced by humanity. Asia in the Global Transition to Net Zero explores what a global net-zero transition could mean for developing Asia. It models emission pathways based on commitments and pledges under the Paris Agreement and compares them with more optimal routes to net zero. The pathways considered will require dramatic transformations in energy and land use, with wide ranging implications. The report finds that early action and international coordination are critical to ensure a low-cost and equitable net-zero transition. With efficient policies, the benefits of the transition from averted climate damages and improved air quality could outweigh climate mitigation costs by five times. Conversely, if policies are not carefully designed, some economies, industries, communities, and populations could be adversely affected. Yet, failure to address the climate crisis would have consequences that would be even more regressive. To avoid these outcomes, deep decarbonization is needed.
